Kel,
Thanks. Tom and I are having a couple of sets fabed up using your example as inspiration. Hope to have some fixtures as a result so they could be more easily reproduced. We have your photos and wanted to be careful not to mess up the critical dimensions. How long are the three inch collectors? Does that matter? Suppose we went to a stepped design, how would that effect the primary length and where should the step from 1 5/8 to 1 3/4 be placed. Idea is same 6000 and below power band with 5.0 stroker and roughly the same heads, carb and cam as you are running. Thanks for the guidance.
Mike
